Mohamedou Ould Slahi was captured in the aftermath of 9/11, accused of being part of Al-Queda, tortured then imprisoned at Guantanamo Bay for 14 years, although never proven guilty. His best-selling book, Guantanamo Diary, describes his abuse at the hands of masked and code-named “Special Projects” interrogators. Now released, Slahi sets out with investigative journalist John Goetz to find those interrogators, including the mysterious Mr. X, in order to seek revenge…by inviting them to tea.
